the tengine makes use of the notifications, if you need an example -  
look there

the crm has a startup delay of max(10s, initdead/2) and an election  
timeout of the same value.
add in some time to check the resources aren't running and thats  
probably where the time is going (assuming you still have initdead set  
to 120s).
